Abstract: A method and apparatus reduce latency of Long Term Evolution (LTE) uplink transmissions. A Downlink Control Information (DCI) message can be received in a first subframe. The DCI message can indicate a resource assignment and a modulation and coding scheme and can indicate a plurality of cyclic shifts from which a User Equipment (UE) may select one cyclic shift for transmission in a second subframe for an uplink carrier. A cyclic shift can be selected from the plurality of indicated cyclic shifts based on a selection criterion. A data packet can be transmitted on a Physical Uplink Shared Channel (PUSCH) in a resource indicated by the resource assignment and modulation and coding scheme using a Demodulation Reference Signal (DMRS) based on the selected cyclic shift in the second subframe on the uplink carrier.

Abstract: A method and apparatus reduce latency of Long Term Evolution (LTE) uplink transmissions. An indication can be acquired, where the indication can indicate a set of frequency domain resource blocks for possible Physical Uplink Shared Channel (PUSCH) transmission in an uplink subframe. A subset of resource blocks can be selected from the set of frequency domain resource blocks for possible PUSCH transmission based on a selection criterion. The selection criterion can use at least a resource set size acquired from the indication, can use a modulo function, and can use an identifier associated with the User Equipment (UE). The PUSCH can be transmitted in the selected subset of resource blocks in the uplink subframe.

Abstract: A configuration can be received that configures a UE with a single configured CSI process for a serving cell. A highest CQI index value can be derived for which a single PDSCH TB with a combination of corresponding modulation scheme and TB size is received with a TB error probability not exceeding a target TB BLER value. The single PDSCH transport block can occupy a CSI reference resource. A CSI request can be received in either a subslot or a subframe. The CSI reference resource can be defined by the subslot in which the CSI request is received if the CSI request is received in the subslot. The CSI reference resource can be defined by the subframe in which the CSI request is received if the CSI request is received in the subframe.

Abstract: Apparatuses, methods, and systems are disclosed for scheduling of transmission time intervals. One apparatus includes a processor that determines a first semi-persistent scheduling resource assignment indicating a first set of resources including a first multiple time domain resources. Each time domain resource of the first multiple time domain resources has a first transmission time interval length. The processor also determines a second semi-persistent scheduling resource assignment indicating a second set of resources including a second multiple time domain resources. Each time domain resource of the second multiple time domain resources has a second transmission time interval length, and the first transmission time interval length is different from the second transmission time interval length. The apparatus includes a transmitter that transmits the first semi-persistent scheduling resource assignment using a first semi-persistent scheduling radio network identifier, and transmits the second semi-persistent scheduling resource assignment using a second semi-persistent scheduling radio network identifier.

Abstract: For collision handling between shortened Transmission Time Interval (sTTI) and Transmission Time Interval (TTI) transmissions, a method determines a collision between user equipment (UE) uplink transmission resources in a first TTI 16 of a first TTI length and uplink transmission resources in a second TTI 16 of a second TTI length. The method further transmits a first uplink data transmission block (TB) in the first TTI and a second uplink data TB in the second TTI. The method interrupts the transmission of the first uplink data TB before transmission of the second uplink data TB. The method receives an indication that indicates whether to resume transmission of the first uplink data TB. The method determines to resume the transmission of the first uplink TB based on the indication.

Abstract: A first resource assignment can be transmitted in a first TTI. First downlink user data corresponding to at least a first transport block in the first TTI in a first set of resources for receiving a first portion of a first downlink user data and second set of resources receiving a second portion of the first downlink user data can be transmitted. The second set of resources can be configured for DCI and can be used instead for downlink user data and the second set of resources may not overlap with the first set of resources. A second resource assignment in a second TTI can be transmitted. Second downlink user data corresponding to at least a second transport block can be transmitted. The second downlink user data can be transmitted in the second TTI in third and fourth sets of resources.

Abstract: A channel state information request requesting a device to feedback channel state information can be received. Whether the channel state information request corresponds to regular latency based operation or reduced latency based operation can be determined. Channel state information can be derived based on a first reference resource when the channel state information request corresponds to regular latency based operation. Channel state information can be derived based on a second reference resource when the channel state information request corresponds to reduced latency based operation. The reduced latency based operation can have a latency less than the regular latency based operation. The derived channel state information can be reported to a network.

Abstract: Control channel candidates can be transmitted in at least one shortened transmission time interval in a subframe and set of resource blocks corresponding to control channel candidates in the at least one shortened transmission time interval. A determination can be made about whether at least one resource block of the set of resource blocks at least partially overlaps with a broadcast control channel or signal. A determination can be made about control resource elements for transmission of a control channel candidate based on the determination about whether the at least one resource block of the set of resource blocks at least partially overlaps with the broadcast control channel or signal. The control channel candidate can be transmitted in the at least one shortened transmission time interval according to the determined control resource elements.
